The fuel filter is intank, infact the fuel pump housing is the fuel filter.
For the symptoms described, seems the Throttle Position sensor is faulty or out of adjustment. It could be the PCM as well.
Get a scan dne to retrieve for trouble codes and let me know the exact code if any found.
The low idling speed is most likely due to a dirty throttle body and IAC. Get them cleaned and retest.
